Our invention relates t``that classI latory commode ,.vehliclesf. by which patients@or,r suchpatients, can be moved temporarily from th r respective beds and onto the seat of said.;ambulatorygvehiclefand in comfortablepositionthereon, said se beingl adjustably raisedr' iov/ered inanticipa'tio '-of'saidihcving of the patient, with respecfto"thelieight:of

the seat, andalsoyinplacillgfthe vehicle in parallel position .relative to the bedrofthe patient. 1`'Ifnet.piltient having been seated as stat' te lavate istiienmoved contigucmsitotI An object of our invention is to provide an ambulatory commode vehicle, comparatively simple in construction, yet having adjusting means whereby the seat of said vehicle may be moved vertically lin either direction so that the patient may be easily moved from the bed and comfortably seated on said vehicle, and whereupon said seat may be lowered when said vehicle is positioned over the toilet bowl as already explained.

A further object of the invention is in the arrangement of the various parts and materials required, making the vehicle easy to manufacture and at reasonable cost.

Other objects will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specication, and wherein similar reference characters designate corresponding parts throughout the several views:

Fig. 1 is a plan view of the ambulatory commode vehicle showing the seat thereof, said seat having the usual type of opening;

Fig. 2 is a side elevation of said commode vehicle on the line 2-2 of Fig. 1;

Fig. 3 is a detail section of a double grooved pulley wheel on the line 3-3 of Fig. l;

Fig. 4 is a detail of a handle for manually rotating said pulley wheel, said detail on the line of Fig. 1;

Fig. 5 shows a, detail of a lead screw shaft, said detail on the line 5,-5 of Fig. 1; and

Fig. 6 is a perspective view of the ambulatory commode vehicle in position over a toilet bowl and showing in dotted line the manner of raising or lowering the seat thereof above said vehicle base.

Said handle is attached to the lever Issa, and said lever in turn is attached to the shaft I9. Integral to the shaft I9 is driving pulley wheel 2I, the latter having two grooves around the periphery thereof. One of said grooves contains the looped pulley cord 23 which is movably engaged thereon, said cord 23 extending over the pulley wheel 20, the latter wheel having a groove on its periphery to receive said pulley cord 23. The second groove of driving pulley wheel 2I has engaged thereon the looped pulley cord 22, said cord extending over the driven pulley wheel 2m in the groove thereon. Said pulley wheel 2 la is provided with a second groove on its periphery in which the pulley cord 23a, is placed and which extends over the driven pulley wheel 20a in the groove thereof.

Integral to the pulley wheel 20, which is positioned underneath the seat I5 as shown in Fig. 2, is a bushing 2I fitted in a bored hole through said'seat l5. A similar bushing is provided for the Wheel 20a.. The wheel 20 has an inner thread which meshes with the outer thread of bushings 21 and 21u. The inner thread of bushings 2l and 2`a meshes with the shaft thread 26. Lead screw shaft 28 is contained within a casing I7, said casing being attached to the seat I5 as seen in Fig. 2. A companion lead screw shaft 28a is mounted opposite to that of the shaft 28, and

. is likewise housed within the casing I'Ia. Said lead screws 28 and 28ar and the casings or coverings thereof are situated respectively at each side of the toilet opening of said seat structure I5, said casings in said relative positions forming handholds thereby enabling a patient needed support while seated on said seat structure I5. The driven pulley Wheel 20a, like the wheel 20,

engages with the screw threads of the shaft 28a.

The casings Il and I'la also function as hand holds for the patient while being moved from the bed to the lavatory or like retiring place.

25 is the housing to enclose the underneath rotating wheels and the pulley cords connected therewith.

The following is a description of the operation of the pulley wheels and pulley cords in connection therewith for the vertical lifting and lowering of the seat I5.

When the handle I8 is turned, the driving wheel 2| likewise turns, being attached to the shaft I9 and the latter to the wheel 2|.

23, thereby causing the wheel 20 tov revolve;

'I'he turningA of the Wheel 2| in turn moves the pulley cord movement Similarly, the turning of the handle I8 and the driving wheel 2| integral thereto will cause the wheel 2Ia to rotate through the medium of the pulley cord 22, which in turn will cause the wheel a to rotate through the medium of the pulley cord 23a. Thus the rotation of the whee1sf20 and 20a on the shafts 28 and 28a, respectively, and underneath the seat l5. will cause said seat structure to raise or lower above said vehicle base in accordance with the rotation of the handle I8, as already explained.

It is obvious that Vvarious modications are possible in our invention from that described in this specication without departing from the spirit thereof. For instance, the wheels and pulley cords connected thereto may be substituted by gears and connecting shafts. or other methods may be employed to manually raise and lower the seat of the vehicle.

Now, having described our invention, what we claim is: Y Y

In a device of the class described, a Wheeled base comprising a pair of spaced side walls and means connecting said side walls at forward and center portions thereof to provide an unobstructed opening between the rear portions of said side walls, a seat spanning said side walls and having a toilet aperture therein, means adjustably supporting said seat for vertical movement over said rear portions. said. supportingr means including a vertical lead screw rotatably mounted on each side wall and fixed against axial relative thereto, and internally threaded bushings rotatably mounted on and extending through said seat, each bushing threadedly receivingvone of said screws, means mounted on said seat for rotating said bushings in unison and a pair of elongated tubular housings, each housing fixed to and extending upwardly from said seat in axial alignment with a cooperating bushing and screw, said housings enclosing portions of corresponding screws which extend above said'seat.
